Uncomfortable feeling

I got the opportunity to preach Sunday night at Gillsville Baptist Church while their pastor is out of town.  This is the church that is allowing us to live in their parsonage for the next 6 months or so while we work on getting the church started.  

I was preaching out of Jeremiah 29 about how God has a purpose for our life and wants us to seek after Him.  I preached for around 30 minutes  but it seemed like an hour and when it was done I wanted nothing more than to rewind time and do it again.  I don't know what it was but I felt like I had done such a disservice to the preaching that it needed to be done again.  Everyone said they enjoyed it and my family said it was good, but of course they will say that.  

As much as I enjoyed being up there and getting to share Gods word at the end it was one of those strange feelings like nothing really flowed and it was just a bunch of gibberish.  It's been two days since and I can't get this feeling to go away I want to preach in such a way that is clear and compelling and that completely honors Christ.  Maybe this is a good feeling that will only push me harder in preparation next time but for now I hate it and wish I could put my finger on what it was that was so off.
